Fluorine Free Foam (F3) has officially replaced AFFF across the Department of Defense fire service - but what does that really mean for firefighters on the line?

In this episode, Matt and Chris sit down with Austin Perry, a Staff Sergeant and Company Officer at Eielson Air Force Base, who brings firsthand operational experience using F3 during two major aircraft responses - an F-35 crash and an F-16 mishap in 2025.

Austin shares insights from both real-world incidents and formal training at the Dallas-Fort Worth Fire Training Research Center, breaking down the science, limitations, and tactical adjustments needed to apply F3 in the field effectively.

From foam chemistry and nozzle techniques to weather effects and decision-making under pressure, this episode dives deep into the technical side of firefighting’s newest challenge: mastering F3.
